I have LastPass which is $6-7 per month but thinking about switching to Apple iPhone Password that’s free, I think.
Yep it is free but sadly limited to passwords only. 1Password allowed you to store Product serial numbers and such. Used it for years when the Data was stored on iCloud.
Passwords allows you to use face or fingerprint, works seamlessly and it is free so jump in. Safari saved passwords in setting so seems like all they did was make an app to display and access them.
